1. Feedback Suppressor: The digital processor chip operates with configuration, automatically detects audio signals, suppresses feedback in all directions, effectively prevents howling noises, improves the device's sound quality, and ensures pleasant audio.2. 5Band Parametric Equalization: The internal circuit utilizes 5band parametric equalization and digital frequency shifting technology to avoid feedback. This effectively increases the microphone distance and prevents feedback. The effective feedback suppression can reach up to 99%.3. 8 Feedback Point Memory: A professional automatic feedback suppression algorithm supports 8 feedback point memory. This ensures feedback protection and more effectively safeguards expensive equipment such as power amplifiers and speakers.4. Versatile Functions: Fully equipped interface, metal snapfit connection technology, and XLR interface ensure signal stability. Various inputs and outputs are available.
